은행업의 시간동인 ABC 모형 개발과 서비스별 원가산정

The recent surge in global competition over service industries has led to a continued effort to reduce costs, improve quality and reach the market faster. An important element of competitive performance is the ability to provide accurate and relevant cost information. Banking business, like many other service industries, has a large portion of common costs across its financial services. Our research explores six major Korean banks’ implementation of the Activity-Based Costing system to improve the accuracy of their costs. The study shows how they identify and measure their activities and cost drivers. Our analysis includes two models, which are ‘real activity-level model’ and ’standardized activity-level model’ based on Time-Driven ABC as suggested by Kaplan and Anderson(2004). This paper is the first study on Time-Driven ABC in Korea incorporating the concept of practical capacity. Using simulations based on these two models, our study demonstrates the different cost assignment results between the two models and also the gap in results occurring from banks’ different organizational structures and strategies. Finally, it discusses the limitations of the ABC system study in the case.
